DEVICE FOR MIXING LIQUIDS.

Specification of Letters Patent.

Application filed June 26, 1919. Serial No. 306,951.

T 0 all whom it may concern:

Be it known that I, HUBERT MEREDI'riI- JONES, a subject of the 'King of Great Brittain, and resident of New York, N. Y., have invented certain new and useful Improvements in Devices for Mixing Liquids, of which the following is a specificatlon My invention is designed to aerate liquids and semi-liquids and it consists in the features and combination and arrangement of parts hereinafter described and particularly pointed out in the claims.

In the accompanying drawings Figure 1 is a side View of a liquid mixing device embodying my invention.

Fig. 2 is an: end elevation of the device.

In these drawings 1 is a tube having at its upper end a head or member 2 fixed rigidly thereto in any suitable manner. This head has a socket 3 to receive the end of the driving spindle of the power transmission device by which the head and the tube are rotated rapidly. The driving head may be connected to the driving spindle in any suitable way, as by set screws 4:.

At the lower end of the tube a head is provided for delivering air into the liquid or semi-liquid to be acted on and mixed; Said head may assume different forms, but in the particular form illustrated it consists of radiating arms 5 formed of tubes communicating with the hollow interior of the tubular stem 1. Air is admitted to the tubular stem 1 through an air port or ports 6 at or near the top of the tubular stem to pass through the tube and to be discharged through the radiating tubular arms 5 as the device is rotated rapidly while immersed in the liquid or semi-liquid. The ends of the arms or tubes are cut at an angle and the direction of rotation of the arms in the liquid to be mixed is indicated by the arrow so that it will be observed that the tendency will be to create a vacuum on the trailin side of the arm or on its inclined side whicii will immediately fill with air coming through the tubular stem and its arm an as this action is constantly going on the air will be drawn constantly from the tubular structure into the liquid to be distributed through the same.

In order to an ment the distribution of the air through tiie liquid I employ means for separating or dividing up the 1iquid,-or semi-liquid, material adjacent the ends oi. the arms from which the air is discharged and while this means may assume various torms I show wires or rods in the form of bails or loops 25 arranged with portions substantially crossing the angular. ends of the radiating tubes, and close to the opening thereof, but not so close as to interfere with the passage of the liquid between the wire or loop and the end of the radiating tube. Obv ously, varied results may be obtained by either arranging the wire or loop forward, or to the rear, of the radiating tube. The function of this wire loop is to break or divide up the liquid and allow the air to m1ngle with the divided portions and quickly distribute through the same, and as this breaking or dividing efi'ect takes place adjacent the point where the air enters the liquid from the radiating tubes a rapid distribution of the air throughout the liquid will be the result.

The invention may be used at soda fountains, or in the kitchen for whipping up various materials such as drinks, cream, eggs, mayonnaise dressing, emulsions, such as made up by druggists, cake batters, and other materials intended to be lightened by the introduction of air throughout the mass.

I cla-im- 1. In combination in a mixer a rotary tube, radiating tubes at the lower end thereof, and communicating with the interior of of the tubes to divide up the material to I receive the air.

2. In combination in a mixer, a rotary tube, a radiating tube at the lower end thereof, and communicating with the interior of the rotary tube for receiving air therefrom, said radiating tube delivering air from its outer end into the material to be mixed, and a wire extending across the end of the tube to divide up the material to receive the air. 3. In combination in a mixer, a rotary tube, a radiating tube at the lower end thereof, having a beveled end, and communicating with the interior of the rotary tube for receiving air therefrom, said radiating tube delivering air from its outer end into the
